IMIJuovLD MACHINE `IoIt FORMING HAVES TItoUeHs.

TO ALL` WHOM IT MAY CONCERN: l l

Be it known that we, ALLEN OALKIS and WILLIAM TOWER, of Almont, Lapeer county, and State of Michigan, have invented a new and useful Improvement in Machines for-Forming Eave Troughs and Conductor Pipes; and we do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the saine, reference being had to the accompanying drawing, forming part of this specification, in whichy Figurcl is a top orplan Vielwof our improved machine. v

Our invention has for its object to furnish an improved machine, by means of .which the manufactureV of eare troughs andconductor pipes may lue-greatly facilitated. i l 'y And it consists, first, in the combination o'f bars` with eachother and ivith the frame of the machine, for thepurpose ofv bending over the edge of the metallic strips to-receive theystitl'ening wire. I

Second, in the combination' of the bars witlieach otheraifd with the frame of the-machine for the purpose of `partially forming the cave troughs.A I

Third, in thc'combination of the dios, sliding head-block,l nippers, rope, shaft, gear-wheels, and-shank' with each other and with the frame of the machine. v v A And fourth, in the combination of the dies, guide-bar, nippers, rope, shaft, gear-wheels, and crank with each and with the frame of the machine. i i

y A is'the frame of the machine; B is a metallic' bar, attached tothe upper edge ofthe frame A of the machine. A narrow groove or channel is-formed between the` bar Band the edge of the frameA, to which it is attached, for the reception' of theedge of .the strip frorn-which the trough or pipe is to be made, asshown in fig.' 5. C is mbar hinged to the edge of the frame A, as shown in iig. 1. D is a bar attached to the sideof the frame A. The upper. side ofthe bar. D- is soshaped as to.give the required 'l'orm to the eave trough. E is a barhiuged to the't'op edge of the fra-nie A,'as shwn in fig'. 5: ,The side of the bar E that shuts down upon the bar D is so formed as to fit the said bar', giving forn'i uo-'t'l-Iestrip of.' metal from which the trough is to be made, by pressing it between the said hars D andi-E. 'Fm-isv a bar hinged to the bar E, 4and which byl being shut down upon'the bar D, gives form to the vertical side` o'f'the trough. G is a block having alslit cut through it ofthe exact form it is desired the trough should have, and bypassing the tr'ough through this slit or die it is brought to the proper form. H is the slidinghead-hlock, whichslidesin a grooveor channel formed upon the upper side of the frame or table A. 'The bloei; H isl madefof such la form as to it into the said trough, and it. has shouldersv t, against which the end edges of the said'trough p'ressas it is drawn 'forward through `the die G. Ihre the nippers by which the end of the trough is grasped to draw it through the die Gf To these nippers is att-ached one end of the rope J, which passesvaroundthepulleyK, pivoted to the end of thc'tahlc or frame A, as shcwn in figs. 1 and 2, and its other end is attached to the shaft L, as shown in' tig. 2. TheV shaft L revolves in bearings in the frame A of the machine, and' to its projecting end is attached the gear-wheel M, the teeth of which mesh into the teeth of the gear-wheel N, to which thecrauk O is attached. P is the die for bringing the conductor pipe into the required-shape. AThe outer part lplof the die? has a circular hole formed through it. p2 is 'a plug or former, whichfis supported within the hole through the part pl bya screw, p3, projecting from its rear side, which passes through a hole in the support R, upon' which screw are placed nuts Sl and S2, by means of which thesaid former p2 is regulated. T is a guide attached to the lower side of the part p1 of the die P, which enters a slot in the lower part ofthe former p2, and which guides the edges of the pipeinto such aposi tion that they will enter the channels between the plates ul andu.2 of the har U, as shown in fig. 5. One end of" the barvU is pivoted to the face -of the former p2, as shown in iig. 3, and the other end rests against a block, V, attached to the frame or table A of the machine. The bar U is square, and is placed with a corner downward, as shown in iig. 5, and t'o the sides adjacent to the lower corner are attache-lthe plates ul and u2, in such` a wayl that channels orgrooves may he formed between the said plates u1 and u2 and the-bar U, for' `the reception of the edges ofthe pipe. The pipe is drawn through the die Pandaroundthe -bar U by the nip'pers I, the rope J of which'passes over the pulley W, and thence'to the shaft L," as before described.

In making eave troughs with this machine the z ine or. other material ot'jvhich the troughs are lto be made is cut into strips about seven feet long, and of the necessary breadth to-form the trough. 4The edgeoi' this strip', is then placed in the channel beneath. the bar B, and the bar, C turned -up into' the position shown in g.5.

This bends the edge of" the strip over upon itselffor the reception o,f the stiffening wire, Whichis thenlput in and the edge closed down upon it. The wired edge is then placed inthe creaseor channel between the bar D and the side of the frame or table A, and the bars E and F ,turned down. 'This partially forms the trough, which is then removed from the bars D -E F, and its end passed through the slit in the Vdie G, and upon the block H, with'its end edgesresting against theshoulders L. Thel end of the trough is-'th'en grasped with the nippers I, and by turning the crank O it is drawn through the die G, which completes its formation. In making conductor pipes, the material ofwhich the pipe is to b e made is cut into -strips about seven'feet long and of the required breadth. The edges aro then turned overby means of thc bars B and C. It is then bent up and passed through the die P, the guide T guiding its turned-over edges into such a position that they Will'pass into Vthe channels'between the plates u1 and u2 and thebar U. The end of the pipe is `then graspedby the nippels I,

and theropeJ passed over the pulley W. Then by turning the crank 0 the pipe is drawn through the pipe P, upon the ba-r U. The bar UisV then turned over and the edges of the pipe soldered, after which it may be removed from the bar U. l

We claim as new, and desire to secure Aby Letters Patent-- 1. The combination of' thebars B and C with cach other, and with the frame A et the machine, substantially as described and for the purpose -set forth. I l l l 2. The combination of the barsd) E F with ',cach other. and with the frame .A of the machine, substantially as described and for the purpose set forth. 'i

3. The combination of the die G; sliding-block I-I, nippers I, rope J, shaft L, gear-wheels MLN", and crank O with each other, and with the frame A oi the machine, substantially'as described and for vthe purpose set forth. p Y

'4'. The combination of the die P, guide T, bar U, nippers I, ropeJ, shaft L, .gear-wheels N, and crank O with each other, and with the frame A of the machin-e, substantially-as described and for the purpose set forth. i
